UNITED STATES JOHN JOHNSTON, OF ST. LOUIS, MISSOURI.

MOP.

Application filed December 15, 1922.

To all whom it may concern:

Be it known that 1, JOHN JOHNSTON, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Mops, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in mops, and has for its object to provide a mop having a belt of suitable material for washing or polishing floor-surfaces and the like, in which successive lengths of said belt are brought into successive contact with the surface being treated, and in which-the belt is reversed when one of its faces has been exhausted, bringing its other face into operative position; the shifting of the successive lengths of the belt, and the shifting from one to the other face of the belt being effected by the manipulation of the mop handle.

The device is also provided with means for dropping oil or water on the surface being treated, the deposit being made at a point adjacent to the operative face of the mop; and it is further provided with means for enabling the mop to be supported, when not in use, for purposes of storage or display and the like.

Drawings.

Fig. 1 is a front elevation of a mop embodying my invention.

Fig. 2 is a detail view of the belt-carrying frame, the latch-frame being shown in section, taken on the line 22 of Fig. 1.

Fig. 3 is a side elevation of the device in its inoperative but supported position.

Fig. 4 is a like view of the same in operative position, illustrating in dotted lines the successive changes of position employed in shifting the operative mopping surfaces.

Description.

In the drawings, the tank 5 is shown as being divided by the wall 6 into a waterohamber 7 and oil-chamber 8, access to said chambers being provided by screw-plugs 9. The handle 10 is mounted upon the tank 5 and extends vertically therefrom.

The water pipe 11 is fed by the water chamber 7 and the flow therethrough is controlled by a valve-rod 12, and drops upon the floor-surface from the open end 13 of said pipe 11.

Serial No. 607,047.

Similarly the oil-pipe 14 is fed by the oilchamber 8, and is controlled, by the valverod 15 and discharges through its open end 16.

The tank 5 is mounted in a frame comprising the standards 17 and, cross-bar'lS: and between said standards 17 is a pivot-allymounted frame G comprising side-arms 19 and the belt-carrying pins 20 and 21.

A U-shaped latch-member H serves to lock the frame G in alinement with the standards 17, as shown in Figs. 1 and 2; the frame G being pivotally connected to said standards 17 by the pins 22. The latchmember 1-1 has its movement limited by its slots 23 and the pins 24 extending through said slots 23 and into the standards 17.

The pin 20 carries the fabric-holding board. 25, while the pin 21 carries the 0pposing board 26.

The rollers 28, 29 and 27, mounted and arranged as shown in Figs. 3 and 4 serve to maintain the proper tension in the fabric as it passes between the boards and 26.

Arms 30 are hinged to the standards 17 as indicated by 31, and at their lower ends hold pivotally the claw-member 32; the pintles 33 being extended inwardly through the slots 34 to be detachably seated in the angular slot 35 in the standard 17; the engagement of said pintles 33 with the slots 35 serving to hold the arms 30 in alinement with the standards 17. An arcuate slotted arm 36, whose movement is limited by the pin 37 on the standard 17, serves to limit the throw of the arms 30 when said arms 30 are disengaged from the standards 17 to serve as a support for the mop, as illustrated in Fig. .3.

The standards 17 carry the guide-wall 38 having the curved slot 39, terminating at its upper end in the straight slot 40; the purpose of these members being to hold the pintles 41, supporting the roller 42, which roller 42 normally rests upon the upper surface of the upper fabric roll (carried by the board 26) and toward the rear edge thereof.

Mode of operation.

The mop'when at rest is in the position shown in Fig. 3, and is supported by the arms 30. The arms 30 are provided with a removable pin 43, to carry a roll 44 of the fabric to be used upon the boards 25-26. The roll 44 being so mounted, its fabric is drawn to the upper board 26, and its forfabric roll carried by "the board 25.

ward edge is secured in one of the slots 4L5 with which the edges of the boards 25 and 26 are provided. The fabric of the roll 44: being wound upon the board 25, the pin 43 is removed, and the fabric is drawn from the board 26 over the rollers 28, 27 and 29 to the board 25, to which the forward end of the fabric is secured by insertion in one of the slots 4L5.

I The mop is then ready for use, the arms 30 are swung into position beside the standards 17 and there locked by means of the engagement of the ,pintles 33 with the slots 35, and by means of the handle '10 the mop F is thrown from the inoperative position illustrated in Fig. 3' to the operative position. shown in full lines in Fig. 4.

In this position the claw 32 rests upon the upper surface of the fabric rolled on the i. board '25, and the mop will be so used as long as desired, oil. water or other liquid being deposited on the floor surface from the tank and the mop being manipulated in the usual manner for cleansing or polishing the floor surface.

The fabric section contacting with the floor having been used to an extent which causes the operator to desire to renew it, that renewal is effected by the movement of the parts diagrammatically shown in Fig. f.

The initial movement is forward (toward the left) on the lines indicated by arrows AA, the claw '32 moving as shown by arrow a to engage with the front edge of lthe 1e position then occupied by the parts is shown in dotted lines at the left of (Fig. 4f, the handle being in an approximately vertical position.

From that position the mop is movedbodily rearwardly, the handle 10 moving in the path shown by arrows BB, the action of the c'law'32, reversing the lower fabric roll being shown by the arrow b. A. continued rearward pull on the handle 10, as indicated by the arrow G accomplishes the complete turning over of the boards and 26, and supplies the lower face of the former with a clean area of fabric.

The handle 10 is then thrust upwardly and forwardly as indicated by the arrow D and the use of the mop on the floor surface is resumed.

During these successive shifts the roller 42 is carried upwardly, guidedby the slots 7 89 and 40, is then released by the rotationof the board 26, drops to the level of the bottom of the .;slot 39 and then rides on the upper surface of the fabric roll carried by the board 26 as before; this movement of the board 26 being indicated by the arrows e and f.

'VV-hen the entire length of fabric has thus been used the frame G is released by operating the latch H (as shown by dotted lines in Fig. 2), frame Gr is reversed end-for-end, and the board 25 is above, loaded with the bulk of the fabric, in position to be fed to the board 26.

These successive operations may be continued indefinitely until the fabric is so worn as to be unfit for further use.

Various changes of structure from the form illustrated and described herein may be made without departing from my invention. But the form of mop-head illustrated a relatively thick base covered by fabric is of special value in the cleansing of the rounded edges of hospital floors because of its fabric-covered forward edge.

Claims.

Having thus fully described my invention, 1 claim-- 1. In a mop, a. frame; a pair of boards rotatably mounted in said frame; a sheet of fabric wound upon one of said boards, and

means for rotating the opposing board to draw said fabric thereon from said firstmounted in. said main frame; a pair of boards rotatably mounted in the opposite ends of said secondary frame; and a sheet of fabric mounted upon said boards and arranged to be wound off of one board and on to the opposing board, and means formain- .taining uniform tension upon said fabric during its passage from one to the other board, said boards being arranged to be held successively in operative contact with the work.

In testimony whereof I have hereunto affixed "my signature.
